The best month to visit Milan is generally May or September. During these shoulder-season months, the weather is pleasantly warm (ranging from 15°C to 24°C) and the city's gardens are in full bloom or transitioning into vibrant autumn colors. These months avoid the oppressive humidity and extreme heat of July and August, when many locals flee to the coast and some smaller shops and restaurants close for the "Ferragosto" holiday. If you are a fashion enthusiast, the best months are February and September for Milan Fashion Week, though you should expect inflated hotel prices and difficulty securing restaurant reservations. For those who enjoy a festive atmosphere, December is magical as the city lights up for the "O bej! O bej!" market and the Christmas season, although the weather can be quite grey and chilly. April is also a standout month for the "Salone del Mobile" (Design Week), which brings a world-class creative energy to the city. Ultimately, May offers the most reliable balance of beautiful sightseeing weather, outdoor dining opportunities, and a manageable level of tourist crowds compared to the peak summer months.
